Patented May 9, 1939 UNITED STATES PATENT OFFICE 4 Claims.

The present invention relates to door checks and has for its principal object the provision of a door check whereby the door may be maintained in an open rigid position so that the same may not be closed either by wind or by any other agency.

A still further object of the present invention is the provision of a door check most suitable for employment in connection with garage doors.

A still further object of the present invention is the provision of a door check consisting of a pair of pivoted arms, one of the arms engaging the door frame while the other engages the door, and

so arranged that said arms may angularly shift when the door is closed and extend when the door is opened, with means upon the door to engage one of said arms when the door remains in an open position, to maintain said arms in a rigid immovable position.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the 5 appended claims.

In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views;

Fig. 1 is a top plan view showing the door in an open position with the door check in an ex tended operative position;

Fig. 2 is a similar view with door closed showing the door check in a folded inoperative position;

Fig. 3 is a perspective view of the door showing the same in an open position with the door check in an extended operative position; and

Fig. 4 is a perspective view of a plate attachable to the door and which is adapted to engage the door check to maintain the same in an operative position when the door is open.

Referring to the present drawing there is shown therein a door frame including a vertical side bar Ill upon which door I l is suspended by means The horizontal upper frame bar is indicated by l3.

Affixed to the under face of the horizontal upper frame bar l3 by means of a plurality of screws I4 is an oblong plate l5 having a free end projecting inwardly into a dwelling or garage and beyond the door frame. Pivotally affixed as at It to the free end of said oblong plate I5 is arm IT. The opposite end of said armll pivotally connects with arm I8 as at l9. Integrally formed at the opposite end of said arm [8 and downwardly projecting therefrom substantially at a right angle is bar 20 terminating in a handle 2| at its lower end. Said bar 20 passes through a pair of brackets 22 positioned adjacent the free edge and on the inner face of door II, to maintain said bar 20 in proximity to the said free edge of door II and in parallel relation therewith, as is clearly seen.in Fig. 3.

Handle 2| remains on a plane co-extensive with arm l8 and is in parallel relation therewith, so that when the door remains in an open position shown in Fig. 1 both said arm l8 as well as said handle 2| remain in an angular relation with the door.

The invention further includes a supporting plate 23 having an integral leg portion 24 by means of which said plate 23 may be mounted upon the inner face of the door by means of screws passing through screw holes 25 in said leg portion 24 of plate 23. Said plate 23 remains at an obtuse angle with relation to leg portion 24 and further is of arcuate formation on a horizontal plane, for the purpose hereinafter stated. Plate 23 has adjacent its upper edge a notch 26 struck out with a resulting lug 21 projecting upwardly and above the upper edge of said plate 23 as is clearly seen in Fig. 4.

From the hereinabove description it will be seen that brackets 22 permit rotary as well as upright shifting movement of bar 253. Thus said bar 20 and bracket 22 constitute pivotal means for the adjacent end of arm I 8.

When door I I remains in a closed position, arms I1 and I8 remain in an angular relation seen in Fig. 2, the same remaining disposed immediately below the lower face of the upper horizontal frame bar l3. In that position arm l8 rests upon the upper edge of plate 23. When the door is shifted into an open position, arms if and I8 shift until the same assume an extended position illustrated in Figs. 1 and 3. During the process of the opening of the door arm l8 shifts upon the upper edge of plate 23 until the door is completely opened at which time said arm 53 will automatically fall within notch 26 of said plate 23, lug 21 constituting a guide preventing displacement of said arm Hi.

In order to close the door, bar 25 is manually shifted in an upward direction for elevating arm I8 from notch 26 for the purpose of bringing said arm above the continuation line of the upper edge of plate 23, and while maintaining said arm l8 in that position, manual pressure is applied at handle 2| toward door I l for the purpose of shifting arm l8 upon the upper edge of plate 23 and for facilitating the respective angular shifting movement of arms I! and I8. On giving a push to door II for the purpose of closing the same, arms I! and I8 will gradually angularly shift, arm 18 riding upon the upper edge of plate 23 toward the inner face of door ll. When the door is completely closed arms I! and I8 will assume the position illustrated in Fig. 2.

When door II is completely opened arm l8 automatically drops into notch 26 due to gravity as well as due to the drag exerted thereupon by bar 20.

Due to the fact that said plate 23 remains at an obtuse angle with relation to leg portion 24 and further due to the fact that said plate 23 is of slight arcuate formation, the portion thereof adjacent its free end, will substantially remain in perpendicular relation with the longitudinal axis of arms I! and 8 when said arms are in extended position, as is clearly seen in Fig. 1. This arrangement will not only facilitate said arm I8 for automatically dropping Within notch 26 when said arms I! and I8 are fully extended at the time the door is fully opened, but will at the same time tend to rigidly hold arm l8 against lateral movement.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

l. A door check comprising a pair of arms pivotally joined together by one of their ends, one of said arms being pivoted to the door frame, a bar integrally formed with the other of said arms and in an angular relation therewith, said bar being pivotally supported upon the door and being adapted for longitudinal shifting movement thereupon, and a plate mounted upon the door and in a transverse relation with said last named arm for supporting the same as the same makes shifting movement to a folded or unfolded position, said plate being provided with a notch at a point of said plate which coincides with said last named arm when the latter remains in an unfolded position for permitting said last named arm to fall therewithin due to gravity of said arm and to the drag exerted thereupon by said bar for the purpose of engaging said arm with said plate for maintaining said arm in a stationary position when the door remains opened.

2. A door check comprising a pair of arms pivotally joined together by one of their ends, one of said arms being pivoted to the door frame, a bar integrally formed with the other of said arms and in an angular relation therewith, said bar being pivotally supported upon the door and being adapted for longitudinal shifting movement thereupon, and a plate mounted upon the door and in a transverse relation with said last named arm for supporting the same as the same makes shifting movement to a folded or unfolded position, said plate being provided with a notch at a point of said plate which coincides with said last named arm when the latter remains in an unfolded position for permitting said last named arm to fall therewithin due to gravity of said arm and to the drag exerted thereupon by said bar for the purpose of engaging said arm with said plate for maintaining said arm in a stationary position when the door remains opened, said bar being adapted for manual longitudinal shifting movement for elevating said arm and bringing the same out of the said notch preparatory to swinging the door into a closed position for the purpose of permitting shifting of said arms into an angular, folded position.
